ABSTRACT
Recent research shows that the functional outcome after an acute Achilles tendon rupture is comparable after conservative versus operative treatment. It is therefore recommended to treat patients conservatively, but strong reasons for surgical treatment exist. In principle, no additional radiographic diagnostic exams are indicated for the diagnosis. An appropriate anamnesis, palpable gap and positive Thompson test have an excellent sensitivity. In case of doubt, an ultrasound should be performed as the first step. A shared decision process should be pursued for establishing treatment plan. However, it is recommended that patients be treated conservatively unless strong arguments for surgical intervention are present. It is important to properly inform patients, and thus manage expectations about the expected rehabilitation process. If there is an increased risk of re-rupture, such as in athletes or during physically demanding work, surgical treatment can be considered. Then a surgical technique in which expertise and experience has been gained should be used as no difference in outcome have been found after open versus minimal invasive techniques.

OBJECTIVE: To investigate the mid-term effect and complications of arthroscopic popliteal tendon suture in the treatment of lateral meniscus injury. METHODS: From January 2016 to December 2020, the data of 57 patients with lateral meniscus popliteal tendon injury treated by arthroscopic popliteal tendon suture fixation were retrospectively analyzed, including 35 males and 22 females, aged from 18 to 47 years old with an average of (32.9±7.9) years old. Knee function was evaluated using the International Knee Documentation Committee (IKDC) and Lysholm scores both before the operation and at the final follow-up. Meniscus healing was evaluated according to the postoperative Barrett standard. Wound healing complications, such as vascular injury, nerve injury, and lower extremity venous thrombosis, were recorded. RESULTS: All 57 patients were followed up for 12 to 58 months with an average of (38.1±14.9) months.The incisions of the patients after the operation were all Grade A healing without infection, popliteal tendon injury, blood vessel injury, nerve injury and lower extremity venous thrombosis.The IKDC score increased from (49.7±3.6) points preoperatively to (88.5±4.4) points in the final follow-up (P<0.05). The Lysholm score increased from (48.8±4.9) points preoperatively to (91.9±3.9) points at the final follow-up (P<0.05). At 3, 6 months and 1 year after operation, according to Barrett's criteria, 54 cases were clinically healed, the healing rate was 94.7% (54/57). CONCLUSION: This study preliminarily confirmed that arthroscopic suture technique can result in clinical stability through suture and fixation of the meniscus in the injured lateral popliteal tendon area. No adverse effects on knee joint function were found in the mid-term follow-up after the operation.

The hand is a unique structure in human body performing complex activities of daily life making it prone to injuries. While operating on zone VI extensor tendon injury, a surprising entity was observed. The extensor digitorum to the right index finger was absent. This is an extremely rare entity in the literature. Also, all previous studies on the extensor digitorum are cadaveric. Our findings are first of its kind intraoperative, incidental, and confirmed on MRI. Thus, it becomes a case report of special worth mentioning in literature.

Achilles tendon reconstruction is an effective method of repairing Achilles tendon rupture defects. We introduce a new approach for Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft. The study aimed to evaluate the clinical role of this new Achilles tendon reconstruction. We retrospectively enrolled patients who underwent Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft for acute Achilles tendon rupture defects from 2016 to 2021. The clinical and radiological results were assessed at the preoperative and the final postoperative follow-up with Visual Analog Score (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) scores and Achilles tendon Total Rupture Scores (ATRS). Besides, at the last postoperative follow-up, the difference in ankle range of motion between the two side of the patients and the incidence of postoperative complications were recorded. Results revealed patients had significantly lower VAS and higher AOFAS and ATRS (P < 0.01). Compared to the healthy ankle, the operative ankle showed significant deficits in ankle range of motion (P < 0.01). Additionally, radiological results showed no noticeable signs of tunnel enlargement in the calcaneus and no patient had re-rupture. Transversal calcaneal anchored Achilles tendon reconstruction with free semitendinosus tendon autograft is an effective treatment option for patients with acute Achilles tendon rupture with large defects and have high postoperative exercise demands.

BACKGROUND: The Achilles tendon is the body's strongest and largest tendon. It is commonly injured, particularly among athletes, accounting for a significant portion of serious tendon injuries. Several factors play a precipitating role in increasing the risk of these injuries. OBJECTIVE: Our objective is to derive and validate a risk calculator for the prediction of incidence of any complication following Achilles tendon repair. METHODS: We used de-identified data from the American College of Surgeons' National Surgical Quality Improvement Project (NSQIP) database from 2005 to 2021. It comprises 7010 individuals who had undergone Achilles tendon rupture repair. Demographic and risk factors information was collected. To develop the calculator, the sample was divided into a derivation cohort (40%) and a validation cohort (60%). Multivariate logistic regression was used for statistical analysis, and a risk calculator for incidence of any complication was derived from the derivation cohort and validated on the remaining 60% of the sample. Patients with missing data were excluded, and the significance level was set at p < 0.05. RESULTS: We analyzed the derivation cohort of 2245 individuals who underwent Achilles tendon repair surgery between 2005 and 2021, with a 5.5% overall complication. Multivariate logistic regression identified anesthesia type, ASA classification, certain co-morbidities (pre-operative dialysis and medication-requiring hypertension), and wound classification as significant predictors of complications. The developed risk calculator model had an area under the curve (AUC) of 0.685 in the derivation cohort and 0.655 in the validation cohort, surpassing the widely used and validated modified frailty index. A cut-off score threshold of 0.06 was established using Youden's index to dichotomize individuals into low and high risk for developing any postoperative complications. CONCLUSION: Our risk calculator includes factors that most significantly affect the incidence of any complication following Achilles tendon repair.

OBJECTIVES: This study aimed to evaluate the biomechanical and histological effects of fluoroquinolones on surgically repaired tendon healing. MATERIALS AND METHODS: The Achilles tendons of 40 Wistar rats (mean weight: 213.5 g; range 201 to 242 g) were bilaterally surgically cut and repaired. The rats were randomly divided into four groups: the first and third groups were designated as control groups and did not receive drug therapy, whereas the second and fourth groups received 300 mg/kg ciprofloxacin for a week after the surgical procedure. The first and second groups had both tendons dissected at the end of the first week, while the third and fourth groups were dissected at the end of the third week. The left tendons were examined biomechanically, while the right tendons were examined histologically. RESULTS: Statistical analysis revealed that the mean maximum tensile forces of tendons in the first and second groups were 5.2±1.84 N (range, 2.9 to 8.5 N) and 11.1±2.65 N (range, 7.3 to 13.9 N), respectively, which was found to be statistically significant (p< 0.05). At the end of the third week, mean maximum tensile forces of the third and fourth groups were determined to be 20.7±5.0 N (range, 22.1 to 29.8 N) and 28.7±4.6 N (range, 22.1 to 36.8 N), respectively, which was also statistically significant (p< 0.05). Histologically, our results were compatible. CONCLUSION: This study demonstrated that ciprofloxacin did not exhibit the expected adverse effects on surgically repaired tendon healing in the early stages but likely contributed to healing in the short term by affecting the inflammatory phase.

BACKGROUND: There are many adhesion barrier materials, cross-linked or non-cross-linked hyaluronic acid (HA), used during surgeries. PURPOSE: This study investigates the efficacy of cross-linked and non-cross-linked HA in preventing Achilles tendon adhesions. We hypothesized that non-cross-linked HA may be more effective than cross-linked HA in preventing Achilles tendon adhesions following injury and repair. METHODS: Twenty male Sprague Dawley rats, totaling 40 legs, underwent Achilles tendon transection and repair. Following the surgery, they were treated simultaneously with cross-linked and non-cross-linked HA formulations. The rats were divided into four groups: a positive control group, a group treated with BMC non-cross-linked HA gel, a group treated with DEFEHERE cross-linked HA gel, and a group treated with ANIKA cross-linked HA gel. Four weeks after surgery, macroscopic evaluation of peritendinous adhesion and histological analysis were conducted to assess the effectiveness of the treatments. RESULTS: Non-cross-linked BMC HA demonstrated superior efficacy in preventing tendon adhesions compared to cross-linked HA and control groups. Histological analysis confirmed reduced adhesion severity in the non-cross-linked HA group (P < 0.05). The findings support the potential of non-cross-linked HA as a treatment to inhibit tendon adhesions. Further research, including clinical trials, is warranted to validate these results in human subjects. CONCLUSIONS: Non-cross-linked BMC HA had significantly lower tendon adhesions parameters and better healing scores in histological analysis than cross-linked HA and control group did. Non-cross-linked HA holds promise as a potential treatment to inhibit the formation of such adhesions.

BACKGROUND: In recent decades, early rehabilitation after Achilles tendon rupture (ATR) repair has been proposed. The aim of this prospective cohort study was to compare different immobilisation durations in order to determine the optimal duration after open surgery for ATR repair. METHODS: This study included 1088 patients (mean age, 34.9 ± 5.9 years) who underwent open surgery for acute ATR repair. The patients were categorised into four groups (A, B, C, and D) according to postoperative immobilisation durations of 0, 2, 4, and 6 weeks, respectively. All patients received the same suture technique and a similar rehabilitation protocol after brace removal,; they were clinically examined at 2, 4, 6, 8, 10, 12, 14, and 16 weeks postoperatively, with a final follow-up at a mean of 19.0 months. The primary outcome was the recovery time for the one-leg heel-rise height (OHRH). Secondary outcomes included the time required to return to light exercise (LE) and the recovery times for the range of motion (ROM). Data regarding the surgical duration, complications, the visual analogue scale (VAS) score for pain, the Achilles tendon Total Rupture Score (ATRS), and the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale score were also collected. RESULTS: The recovery times for OHRH, LE, and ROM were significantly shorter in groups A and B than in groups C and D (P < 0.001). The VAS scores decreased over time, reaching 0 in all groups by 10 weeks. The mean scores in groups A and B were higher than those in the other groups at 2 and 4 weeks (P < 0.001), whereas the opposite was true at 8 weeks (P < 0.001). ATRS and the AOFAS Ankle-Hindfoot scale score increased across all groups over time, showing significant between-group differences from weeks 6 to 16 (P < 0.001) and weeks 6 to 12 (P < 0.001). The mean scores were better in groups A and B than in groups C and D. Thirty-eight complications (3.5%) were observed, including 20 re-ruptures and 18 superficial infections. All complications were resolved at the last follow-up, with no significant between-group differences. CONCLUSIONS: Immobilisation for 2 weeks after open surgery for ATR repair may be the optimal strategy for early rehabilitation with relatively minimal pain and other complications.

Aims: Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients. Methods: This was a retrospective study involving 30 patients with an irreparable SSC tear and those with a SSC tear combined with a reparable supraspinatus tear, who underwent a latissimus dorsi tendon transfer. Clinical scores and active range of motion (aROM), SSC-specific physical examination and the rate of return to work were assessed. Radiological assessment included recording the acromiohumeral distance (AHD), the Hamada grade of cuff tear arthropathy and the integrity of the transferred tendon. Statistical analysis compared preoperative, short-term (two years), and final follow-up at a mean of 8.7 years (7 to 10). Results: There were significant improvements in clinical scores, in the range and strength of internal rotation and aROM compared with the preoperative values in the 26 patients (87%) who were available for long-term follow-up. These improvements were maintained between short- and long-term follow-ups. Although there was a decreased mean AHD of 7.3 mm (SD 1.5) and an increased mean Hamada grade of 1.7 (SD 0.5) at final follow-up, the rate of progression of cuff tear arthropathy remained low-grade. Comparison between the isolated SSC and combined SSC and reparable supraspinatus tear groups showed no significant differences. At final follow-up, one patient (3.8%) had undergone revision surgery to a reverse shoulder arthroplasty (RSA). No neurological complications were associated with the procedure. Conclusion: Latissimus dorsi transfer for an irreparable SSC tendon tear resulted in a significant clinical improvement, particularly in pain, range and strength of internal rotation and aROM, which were maintained over a mean of 8.7 years following surgery. Given that this was a long-term outcome study, there was a low-grade progression in the rate of cuff tear arthropathy. Thus, the long-term clinical efficacy of latissimus dorsi tendon transfer in patients with irreparable SSC was confirmed as a joint-preserving procedure for these patients, suggesting it as an effective alternative to RSA in young, active patients without degenerative changes of the glenohumeral joint.

Flexor tendon injuries require surgical repair. Early repair is optimal, but staged repair may be indicated for delayed presentations. Zone II flexor tendon injuries are the most difficult to achieve acceptable outcomes and require special attention for appropriate repair. Surgical techniques to repair flexor tendons have evolved over the past several decades and principles include core strand repair using at least a 4 strand technique, epitendinous suture to add strength and gliding properties, and pulley venting. Early postoperative active range of motion within the first 3 to 5 days of surgery is essential for optimizing outcomes.

CASE: A 58-year-old, very active man sustained bilateral isolated teres major (TM) tendon tears when his arms were forcefully elevated overhead while wakeboarding. Staged surgical repair was performed. A progressive rehabilitation protocol was followed, and he returned to high-level activities 7 months postoperatively. At 1-year follow-up, outcome measures for bilateral shoulders were DASH 0, SST 12, ASES 100, and EQ-5D 1.0. CONCLUSION: Despite literature supporting conservative treatment, this case demonstrates that operative treatment of acute, isolated TM tears can result in highly successful outcomes for motivated active patients.

PURPOSE: This study highlights the pattern of presentation, treatment, early functional outcome, and complications observed in the management of chronic patellar tendon ruptures using our preferred technique of autogenous semitendinosus graft reconstruction. METHODS: This was a retrospective case series involving consecutive patients who underwent patellar tendon reconstruction and met the inclusion criteria. The outcome measures were determined by the post-operative knee range of motion (R.O.M), the post-operative International Knee Documentation Committee (IKDC) score, and pattern of post-operative complications. RESULTS: Nine patients were included in this case series. The mean age of the patients was 35.4 ± 6.8 years (range 27-44 years). Trauma to the knee accounted for majority of the cases (62.5%). Six (66.7%) of the nine patients suffered a patellar tendon rupture from contact injury during sporting activities. The mean length of time from injury to presentation was 20.5 ± 11.2 weeks (range 6-69.5 weeks). Normal knee function in a case (11.1%), nearly normal knee function in 7 cases (77.8%), and abnormal knee function in a case (11.1%) were recorded as a measure of outcome of surgery. The mean post-operative IKDC score was 70.0 ± 6.1 (range 55-77), which was higher than the mean pre-operative score of 26.4 ± 5.1 (range 18-32). The post-operative knee R.O.M averaged 97.2 ± 16.2° (range 70-120°) with a single case with a 10° extension lag noted. CONCLUSION: Normal to near-normal knee function was obtained with the treatment of chronic patellar tendon rupture in the majority of cases using autogenous semitendinosus graft for patellar tendon reconstruction in our series.

Flexor tendon injuries are complex, and management of these injuries requires consideration of the surgical timing, injury location, approach, and soft tissue handling. Complications are common, including adhesions, tendon rupture, infection, and a high reoperation rate for zone 2 repairs. Special considerations are given to chronic ruptures, concomitant fractures, and pediatric cases. We discuss current concepts that may improve patient outcomes.

BACKGROUND: Operative treatment is widely used for acute proximal hamstring avulsions, but its effectiveness compared with that of nonoperative treatment has not been shown in randomized trials. METHODS: In this noninferiority trial at 10 centers in Sweden and Norway, we enrolled patients 30 to 70 years of age with a proximal hamstring avulsion in a randomized trial and a parallel observational cohort. Treatments were operative reinsertion of the tendons or nonoperative management. The primary end point was the Perth Hamstring Assessment Tool (PHAT) at 2 years of follow-up. Secondary outcomes included scores on the Lower Extremity Functional Scale (LEFS). RESULTS: A total of 119 patients were enrolled in the randomized trial and 97 patients in the observational cohort. In the per-protocol analysis of the randomized trial, the mean (±standard deviation) PHAT scores were 79.9±19.5 and 78.5±19.4 in the operative and nonoperative groups, respectively (PHAT scores range from 0 to 100, with higher scores indicating higher function). The prespecified noninferiority limit of 10 points was not crossed (mean difference, -1.2; 95% confidence interval [CI], -8.6 to 6.2; P=0.009 for noninferiority). Analyses of secondary outcomes, including a mean difference in the LEFS score of -1.6 (95% CI, -5.2 to 2.0), aligned with the primary outcome. The observed numbers of adverse events in the randomized trial were nine in the operative group versus three in the nonoperative group (odds ratio, 0.3; 95% CI, 0.1 to 1.2). In the analysis of the observational cohort, the mean PHAT score difference between the nonoperative and operative treatment groups was -2.6 (95% CI, -9.9 to 4.6). CONCLUSIONS: In patients 30 to 70 years of age with proximal hamstring avulsions, nonoperative treatment was noninferior to operative treatment.

CASE: Traumatic pediatric Achilles ruptures are rare, and few cases have been reported among patients with a history of Achilles tenotomy. A 17-year-old boy with a history of Achilles tenotomies for congenital clubfoot as an infant presented with acute midsubstance Achilles tendon rupture of the right leg. The gastrocnemius fascia was dissected to allow for approximation of the ruptured Achilles tendon segments. Furthermore, the plantaris tendon was harvested and sutured around the Achilles tendon-rupture site to improve strength. CONCLUSIONS: Patients with a history of clubfoot and chronic Achilles tendon pain should be alerted to the risk of Achilles tendon rupture.

BACKGROUND: The study aimed to determine the grade of retraction and atrophy according to the time elapsed in traumatic isolated full-thickness supraspinatus (SS) tears in young patients. METHODS: One thousand twenty-six patients, who underwent arthroscopic shoulder surgery, were retrospectively reviewed. Pre-operative magnetic resonance imaging (MRI) of 69 patients aged 18 to 40 years with isolated traumatic full-thickness SS lesions remaining after exclusion criteria were evaluated for tendon retraction and atrophy grades. SS retraction was determined from a T2-weighted oblique coronal MRI slice, and the atrophy grade was determined from the T1-weighted oblique sagittal MRI slice. The patients were divided into four groups 0-1 month, 1-3 months, 3-6 months, and 6-12 months according to the time between trauma and MRI. The relationship of tendon retraction and muscle atrophy with elapsed time was evaluated, in addition, comparisons between groups were made. RESULTS: Thirty-one (45%) of the patients were female and their mean age was 30 ± 7.3 (18-40) years. The mean age of men was 30.5 ± 6.9 (18-39) years (p = 0.880). The time between rupture and MRI was moderately correlated with retraction and strongly correlated with atrophy grades (r = 0.599, 0.751, respectively). It was observed that there was a statistically significant difference between the 1st (0-1 month) and 2nd (1-3 months) groups (p = 0.003, 0.001, respectively), and between the 2nd and 3rd (3-6 months) groups (p = 0.032, 0.002, respectively), but there was no significant difference between the 3rd and 4th (6-12 months) groups (p = 0.118, 0.057, respectively). In addition, there was a moderate correlation between tendon retraction and atrophy grades (r = 0.668). Power (1- b) in post hoc analysis was calculated as 0.826. CONCLUSIONS: The current study, supported by arthroscopy, showed that there is a moderate and strong positive correlation between the time elapsed after trauma and the level of retraction and degree of atrophy in traumatic full-thickness SS tears, and demonstrated the importance of early surgical intervention in young patients.

BACKGROUND AND PURPOSE: The aim of our study was to assess the regional variations in Achilles tendon rupture incidence and treatment methods in Finland during the period 1997-2019. METHODS: The Finnish National Hospital Discharge Register (NHDR) and the Finnish Register of Primary Health Care Visits (PHCR) were searched to identify all adult patients diagnosed with Achilles tendon rupture during our study period. The population-based annual incidence and incidences of surgically and non-surgically treated Achilles tendon ruptures were calculated for each hospital district. RESULTS: Achilles tendon rupture incidence increased from 17.3 per 105 person-years in 1997 to 32.3 per 105 in 2019. The mean incidence of Achilles tendon ruptures ranged from 26.4 per 105 (North Savo) to 37.2 per 105 (Central Ostrobothnia). The incidence of Achilles tendon ruptures increased in all areas. The proportion of non-surgical treatment of Achilles tendon ruptures ranged in 1997 from 7% (Vaasa) to 67% (Åland) and in 2019 from 73% (Southwest Finland) to 100% (East Savo, Kainuu, Länsi-Pohja, Åland). During the study period, a shift towards non-surgical treatment was evident in all hospital districts. CONCLUSION: Regional variations in Achilles tendon rupture incidence exist in Finland; however, the incidence increased in all areas during the follow-up period. More Achilles tendon rupture patients are currently being treated non-surgically throughout the country.
